[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figures 1-6This application provides a bag filter dust slurry device, including a dissolving tank 1, an intermediate storage tank 2, and a granulation buffer tank 3. Four equally spaced, annularly distributed bag filter dust inlet pipes 4 are fixedly installed on the top of the dissolving tank 1. Each of the four bag filter dust inlet pipes 4 is fixedly equipped with a solenoid valve 5. The bottom ends of the four bag filter dust inlet pipes 4 extend into the dissolving tank 1. The end of each bag filter dust inlet pipe 4 away from the dissolving tank 1 is fixedly connected to a bag filter used for dust collection in the production workshop. A stirring assembly is provided on the dissolving tank 1. The stirring assembly includes... The system includes a motor 6, a vertical shaft 7, and multiple agitators 8. The motor 6 is fixedly installed at the top center of the powder melting tank 1, with its output shaft extending into the tank. The vertical shaft 7 is also fixedly installed at the output shaft end of the motor 6. The multiple agitators 8 are all fixedly installed on the vertical shaft 7 and evenly distributed. The motor 6 controls the rotation of the vertical shaft 7 and the multiple agitators 8. The multiple agitators 8 can be used to stir and mix the material in the powder melting tank 1 evenly, achieving the effect of slurrying the powder. The powder melting tank 1 contains a dust... The dust dispersion component is used to evenly distribute dust within the powder dissolving tank 1. The dust dispersion component includes four connecting rings 11, four mesh-shaped dispersing covers 12, a main gear 13, and four auxiliary gears 14. The four connecting rings 11 are rotatably mounted on the bottom ends of their respective bag dust inlet pipes 4 via bearings 10. The tops of the four mesh-shaped dispersing covers 12 are all open, and the four mesh-shaped dispersing covers 12 are fixedly installed on the bottom ends of their respective connecting rings 11. The main gear 13 is fixedly mounted on the vertical shaft 7, and the four auxiliary gears 14... 4 are fixedly mounted on the corresponding connecting rings 11. The four auxiliary gears 14 mesh with the main gear 13. The meshing transmission between the main gear 13 and the four auxiliary gears 14 can drive the four connecting rings 11 to rotate, so that the mesh-shaped distribution cover 12 fixed at the bottom of the connecting rings 11 rotates accordingly. This will evenly distribute the dust entering from the dust inlet pipe 4 of the bag filter into the powder dissolving tank 1. Compared with the traditional method, this greatly improves the uniformity of dust dispersion in the powder dissolving tank 1, which is helpful for subsequent powder dissolving operations and improves the quality and efficiency of pulping.

[0025] In this embodiment, a horizontal partition 9 is fixedly installed inside the powder dissolving tank 1. The main gear 13 and four auxiliary gears 14 are all located above the horizontal partition 9. A through hole 1 is opened at the center of the top of the horizontal partition 9, and the top of the vertical shaft 7 passes through the through hole 1. Four through holes 2 are evenly spaced and distributed in a ring at the top of the horizontal partition 9, and the bottom ends of the four connecting rings 11 pass through the corresponding through holes 2. The design of the horizontal partition 9 separates the main gear 13 and the four auxiliary gears 14 from the powder dissolving area below, which not only ensures the stable operation of the transmission components, but also avoids excessive powder dissolving. To prevent interference from the process, a sealing ring 15 is fixedly installed on the inner wall of the through hole 1. The vertical shaft 7 is rotatably sealed with the through hole 1 through the sealing ring 15. A sealing ring 2 16 is fixedly fitted on the outer wall of each of the four connecting rings 11. The outer ring wall of the four sealing rings 2 16 slides and seals against the inner wall of the corresponding through hole 2. The design of the sealing ring 15 and the sealing ring 2 16 can seal the vertical shaft 7 with the through hole 1 and the connecting ring 11 with the through hole 2 respectively, effectively preventing dust and solution leakage and ensuring the stability and safety of the device operation.

[0026] In this embodiment, an agitation assembly 2 is provided on the intermediate storage tank 2. The agitation assembly 2 includes a motor 219, a vertical shaft 20, and multiple agitator blades 21. The motor 219 is fixedly installed at the top center of the intermediate storage tank 2, and the output shaft of the motor 21 extends into the intermediate storage tank 2. The vertical shaft 20 is fixedly installed at the output shaft of the motor 21. The multiple agitator blades 21 are all fixedly installed on the vertical shaft 20 and are evenly distributed. The motor 219 is used to control the rotation of the vertical shaft 20 and the multiple agitator blades 21, so as to stir and mix the slurry solution in the intermediate storage tank 2 evenly, avoid the slurry solution stored in the intermediate storage tank 2 from being static for a long time and causing precipitation and stratification, so as to ensure that the slurry solution in the intermediate storage tank 2 is evenly transferred to the granulation buffer tank 3, thus ensuring the quality of subsequent granulation.

[0027] In this embodiment, multiple online pH meters 22 are fixedly installed on the outer wall of the intermediate storage tank 2, and the detection ends of the multiple online pH meters 22 are all located inside the intermediate storage tank 2. Multiple conductivity sensors 23 are fixedly installed on the inner wall of the intermediate storage tank 2, and the pH value and ion concentration of the slurry in the intermediate storage tank 2 can be monitored in real time and accurately. This allows operators to understand the changes in the properties of the slurry in a timely manner, and the acid-solid ratio of the slurry can be calculated, providing data for adjusting the pulping process. To ensure the stability and consistency of pulp quality, the acid-solid ratio of the pulp in the intermediate storage tank 2 can be more accurately obtained through the combined action of multiple evenly distributed online pH meters 22 and conductivity sensors 23. When the acid-solid ratio of the pulp solution reaches about 68.5%, it can be pumped to the granulation buffer tank 3 for subsequent spray granulation. A discharge pipe 17 is fixedly installed on one side of the granulation buffer tank 3, and a solenoid valve 18 is fixedly installed on the discharge pipe 17. The design of the discharge pipe 17 and the solenoid valve 18 facilitates the subsequent discharge of the pulp solution for spray granulation.

[0028] In this embodiment, a slurry transfer assembly is provided between the melting tank 1, the intermediate storage tank 2, and the granulation buffer tank 3. The slurry transfer assembly includes a transfer pump 26, a four-way connector 27, three suction pipes 28, three solenoid valves 29, a four-way connector 30, three conveying pipes 31, and three solenoid valves 32. The transfer pump 26 is located behind the intermediate storage tank 2. The inlet end of the four-way connector 27 is fixedly connected to the suction end of the transfer pump 26. One end of each of the three suction pipes 28 is fixedly connected to one of the three outlet ends of the four-way connector 27, and the other ends of each suction pipe 28 are fixedly connected to the melting tank 1, the intermediate storage tank 2, and the granulation buffer tank 3, respectively. The three solenoid valves 29 are fixedly installed on their respective suction pipes 28. The four-way connector 30... The inlet end is fixedly connected to the discharge end of the transfer pump 26. One end of each of the three conveying pipes 31 is fixedly connected to the three output ends of the four-way pipe connector 2 30. The other ends of the three conveying pipes 31 are fixedly connected to the melting tank 1, the intermediate storage tank 2, and the granulation buffer tank 3, respectively. Three solenoid valves 4 32 are fixedly installed on the corresponding conveying pipes 31. Through the cooperation of the transfer pump 26, the four-way pipe connector 1 27, the four-way pipe connector 2 30, and multiple suction pipes 28, solenoid valves 3 29, conveying pipes 31, and solenoid valves 4 32, the slurry solution can be flexibly transported and mixed between the melting tank 1, the intermediate storage tank 2, and the granulation buffer tank 3 according to actual production needs, which improves the overall operating efficiency and production flexibility of the device and adapts to diverse production processes.

[0029] In this embodiment, multiple evenly distributed observation holes are provided on the outer wall of the intermediate storage tank 2. A transparent observation mirror 24 is fixedly installed in each of the observation holes. The design of the observation holes and the transparent observation mirror 24 allows the operator to directly observe the slurry condition and storage volume in the intermediate storage tank 2. When the slurry solution in the intermediate storage tank 2 reaches a certain volume, it can be transferred to the granulation buffer tank 3. A feeding hole is provided on the top of the intermediate storage tank 2. An end cap 25 is screwed into the feeding hole. The design of the feeding hole and the end cap 25 makes it convenient to add the required materials or additives to the intermediate storage tank 2 when necessary, so as to maintain the acid-solid ratio of the slurry solution and meet the requirements of standardized slurry.

[0030] In this embodiment, it should be noted that solenoid valve 5, motor 6, solenoid valve 18, motor 19, online pH meter 22, conductivity sensor 23, feed pump 26, solenoid valve 29, and solenoid valve 32 can all be purchased on the market or customized in the factory. Their wiring connection and control methods are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in this article.

[0031] With the above structure, when the bag filter dust slurry device provided in this application needs to be used for dust slurrying, firstly, open the solenoid valve 32 on the conveying pipe 31 connected to the powder dissolving tank 1, and open the solenoid valve 29 on the suction pipe 28 connected to the granulation buffer tank 3, control the operation of the transfer pump 26, and transfer the slurry solution in the granulation buffer tank 3 to the powder dissolving tank 1. After transferring an appropriate amount of slurry solution into the powder dissolving tank 1, stop the operation of the transfer pump 26, and close the above-mentioned solenoid valve 29 and solenoid valve 32.

[0032] Next, open the four solenoid valves 5, and the dust collected in the filter bag can enter the powder dissolving tank 1 through the four filter bag dust inlet pipes 4. Then start the motor 6, and its output shaft drives the vertical shaft 7, multiple stirring blades 8 and the main gear 13 to rotate. Under the meshing transmission action of the four auxiliary gears 14 with the main gear 13, the four connecting rings 11 can be controlled to rotate simultaneously. The rotation of the four connecting rings 11 will drive the mesh-shaped distribution cover 12 fixed at its bottom to rotate as well. The dust entering from the filter bag dust inlet pipe 4 can be evenly and comprehensively distributed in the powder dissolving tank 1 and mixed with the slurry solution under the action of the rotating mesh-shaped distribution cover 12. At this time, through the rotation of multiple stirring blades 8, the dust and slurry solution can be quickly and efficiently stirred and mixed evenly for slurry treatment. After the dust and slurry solution are stirred and slurried in the powder dissolving tank 1, stop the motor 6 and close the four solenoid valves 5.

[0033] Then, open the solenoid valve 29 on the suction pipe 28 connected to the dissolving tank 1, and open the solenoid valve 32 on the conveying pipe 31 connected to the intermediate storage tank 2. Control the transfer pump 26 to run, and the slurry solution in the dissolving tank 1 can be transferred to the intermediate storage tank 2 for temporary storage. After all the slurry solution in the dissolving tank 1 has been transferred to the intermediate storage tank 2, stop the transfer pump 26 and close the solenoid valves 29 and 32. During the storage of the slurry solution in the intermediate storage tank 2, control the motor 19 to run. The motor 19 controls the vertical shaft 20 and multiple stirring paddles 21 to rotate, thereby agitating the slurry solution in the intermediate storage tank 2. The mixture is stirred evenly to prevent sedimentation and stratification of the slurry solution stored in the intermediate storage tank 2 due to prolonged stagnation. This ensures that the slurry solution in the intermediate storage tank 2 is evenly transferred to the granulation buffer tank 3, guaranteeing the quality of subsequent granulation. By utilizing multiple online pH meters 22 and multiple conductivity sensors 23, the pH value and ion concentration of the slurry solution in the intermediate storage tank 2 can be monitored in real time and accurately. The acid-solid ratio of the slurry solution can then be calculated. During storage, the required materials or additives can be added to the intermediate storage tank 2 through the feeding hole by unscrewing the end cap 25 to maintain the acid-solid ratio of the slurry solution and meet the requirements of standardized slurry.

[0034] When the slurry solution stored in the intermediate storage tank 2 reaches a certain volume and the acid-to-solid ratio of the slurry solution reaches about 68.5%, open the solenoid valve 29 on the suction pipe 28 connected to the intermediate storage tank 2 and open the solenoid valve 32 on the conveying pipe 31 connected to the granulation buffer tank 3. Control the operation of the transfer pump 26 to transfer the slurry solution in the intermediate storage tank 2 to the granulation buffer tank 3, and then the subsequent spray granulation operation can be carried out.

[0035] The advantages of this technical solution are: by transferring the slurry solution in the granulation buffer tank 3 to the powder dissolving tank 1, the bag filter dust is directly dissolved. The uniformly dissolved slurry solution in the powder dissolving tank 1 is then transferred to the intermediate storage tank 2 for storage and measurement of the acid-to-solid ratio. The slurry solution with a qualified acid-to-solid ratio is then transferred back to the granulation buffer tank 3, providing better conditions for subsequent spray granulation, which is conducive to improving product quality. Furthermore, it eliminates the need for re-concentration in the pre-concentration tank of the evaporator, greatly reducing the steam consumption of the evaporator, saving steam resources, and achieving good energy-saving effects.
